Looking for a Keynote-like app that allows for speaker notes editing and viewing

I intend to use my iPad (still in Hong Kong, unfortunately) for class, and I'd like to be able to take notes in the notes portion of PowerPoint files. Unfortunately, I read that Keynote does not have that functionality (and in fact strips out the notes when presentations are imported to the iPad).

Do QuickOffice or Documents to Go allow for the editing of "notes" in .ppt files or is there an alternative app you'd like to recommend?

Thanks!
